Swiss Arms SG 553 R (7.62x39)

Range report? :-)

Hopefully this weekend.

Got my Form 1 back on my 553R. My suppressor for it is in jail, which also has the muzzle device with it. As soon as that gets out of jail I will zero it at 50 yards with the Aimpoint T2 and some 8M3. That will make for a very deadly HD weapon. I figured I would wait a little bit until I can get the true zero with the suppressor. When shooting unsuppressed I will just accept the POI shift.

PNorris, what suppressor and muzzle device are you using? I'd like to get a suppressor, but I honestly don't know much about them. I do have a TiRant 9 that I use on some of my pistols. Are you going with one that threads on or one of those 3-lug type. From the videos I've seen, the 3-lug type seems very secure, but I've never seen one in person.

[PNorris]

I am getting this one. https://www.silencershop.com/griffin...t-review-block I am pretty sure, however, that any good 30 Caliber suppressor will work. This one just had some really good reviews and I liked the QD system it comes with the muzzle device. You can also use the suppressor on 5.56 rifles as well.

Is there enough of a shoulder on the end of the threaded barrel to allow for use of shims with a Surefire SOCOM flash hider? I have a SOCOM 762 suppressor that might work well with this rifle.

I just watched the LAV video. It sucks you can’t at least lock the bolt back (I realize AK mags don’t have a bolt hold open).

Is JDI going to import spare bolts and bolt carriers? I only see 556 stuff and one 762 firing pin on their website.

What exactly would tell you if there's enough of a shoulder? I can measure the diameter at the shoulder and the outside diameter of the threads.

He seems to order stuff from them on a regular basis, so I don't think it would hurt to ask. Obviously the market for 7.62x39 and 7.62x51 is much smaller that 5.56x45, so it would probably just depend on whether he thinks there's enough of a market for it or not. It all seems so well made to me that I'm not worried about bolts or carriers breaking. In fact, I've never seen either break on a regular factory made AK (excluding recent US made parts). If you had to replace a bolt, I'm not sure how the headspacing would work. Are they drop in or would they have to be fitted like a typical AK?

Thanks for the reply.

7.62 shims are 0.750" OD, 0.625" ID.

I guess I should call JDI and ask about parts. A friend of mine has like 3-4 if these Sig 553 type rifles and spent a fortune to buy spare parts. For my purposes, a Bulgarian AK tuned by Rifle Dynamics may work just as well, but the Sig has a far better optics rail. I could see the Sig being the perfect 7.62 Soviet hog gun (and deer for that matter)........assuming if I ever get time to hunt again with my job :-(

7.62 shims are 0.750" OD, 0.625" ID.

The diameter at the threads is 0.615". The outside diameter of the shoulder is 0.787". The length from the muzzle to the shoulder is 0.64". Based on mine, I think the shims should fit.

If you can afford the 553R, then get it. I have it and several Arsenal AK's. There is no comparison when it comes to quality and reliability.

I figured I might as well post here as well:

I have a question concerning green cheek rests if someone could possibly help.

Mr Vickers seemed to have had one in his 553R video, but where in the world could one of these be found -preferably new?

Also, I have one of the older WEZ "triple diamond" green ones, but know little to nothing about them or their years of manufacture -and Guisan's knowledge is no longer.. Any information concerning these would be greatly appreciated as well.
Here's a dusty pic!
